Fabio Quartararo believes 'it is too early' to say whether he is happy or not with the new Yamaha V4 engine.

The Valencia MotoGP Test saw all the Yamaha riders get the opportunity to experience their new V4 Yamaha M1 at the Circuit Ricardo Tormo.

Fabio Quartararo was the top Yamaha rider during the Valencia Test as he ended the day in 15th place with a 1:29.927.

When he last tested the V4 engine at Misano, Quartararo was not impressed, but after the Valencia Test, he found small improvements.

"It’s too early to say whether I’m happy or not," Quartararo said.

"We didn’t make many laps. We, for me, spent a lot of time changing many things on the setting because we clearly missed our strongest point, which is the front feeling.

"So, this is why we spent a lot of time in the garage. We tried to change many things. Luckily, tomorrow we have one more day. Hopefully it’s not raining, but it’s going to be an important day.

"Today was a really short day. We didn’t have time; it was all in a rush, just trying to make the bike work. So, like I said, tomorrow is going to be important, especially to find the way with chassis, electronics, engine, and aerodynamics.

"Today was just a day to be back a bit with the bike, trying to understand a bit more, because the riding style is different compared to the four-inline. But, I like the way of riding on the V4."

However, when asked if the Valencia Test gave him hope for the future of Yamaha's MotoGP V4 project, he said no because he was not able to push the limits with both the inline-four and V4 engine.

"No, not yet," he explained.

"Because this morning was just I did two laps with the standard bike, with the medium tyre, with quite a lot of fuel. This afternoon was soft/soft tyres, trying to find the limit.

"And it was half a tenth better. So, it’s too early. We need to work hard and give the best direction to the engineers to feel what they can do."
